LQL3051HT HART type board
Product Overview
The LQL3051HT is a high cost-performance product suitable for signal conversion of resistive-type signals such as reed switches and magnetoresistive sensors. It utilizes an industrial-grade 24-bit independent Σ-△ analog front-end to ensure high measurement accuracy. Comprehensive protection against surges and reverse polarity prevents misinstallation and mishandling during engineering applications. Enhanced software safety features include low-voltage monitoring reset and multi-task scheduling optimization. All components are industrial-grade, ensuring long service life and stability. To facilitate bulk inventory management for key clients, configuration can be performed using buttons or HART communication devices.
